O52 Tool Standard Test Plug 1-3/4" 1-1/2" Thread Open

Manufacturer Part Number: O52

Anderson Manufacturing Standard Open Test Plug Open stem plugs use the same straight-sided rubber, large wing-nuts, and corrosion free materials as Closed plugs except they have an opening that passes through the center of the stem. This opening allows introduction of air or water pressure into the system you are testing. National pipe threaded tops make these versatile tools easy to set up for pressure testing, clearing blocked lines, or blowing out lines for winterization. This Standard Open Plug has a ¼” hole through the center of the plug stem. The plug top is a combination 1/8" pipe thread and 3/8" hose barb.
